Izinombolo zeFibonacci

Izinombolo zeFibonacci kuwukulandelana kwezinombolo eziqala ngamadijithi u-0 no-1, futhi inani ngalinye elilandelayo liyisamba salezi ezimbili ezedlule.

I-Fibonacci Sequence Formula

Ngokwesibonelo:

• F₀ = 0
• F₁ = 1
• F₂ =F₁+F₀ = 1+0 = 1
• F₃ =F₂+F₁ = 1+1 = 2
• F₄ =F₃+F₂ = 2+1 = 3
• F₅ =F₄+F₃ = 3+2 = 5

Isigaba Segolide

Isilinganiso sezinombolo zeFibonacci ezimbili ezilandelanayo siguqulela esilinganisweni segolide:

lapho φ isilinganiso segolide = (1 + √5) / 2 ≈ 1,61803399

Ngokuvamile, leli nani lifinyezwa lifike ku-1,618 (noma 1,62). Futhi ngamaphesenti ayindilinga, ingxenye ibonakala kanje: 62% kanye 38%.

Ithebula Le-Fibonacci Sequence

Imisebenzi ye-C-code (C-code).

i-fibonacci ephindwe kabili(int n engasayiniwe) { double f_n =n; kabili f_n1=0.0; kabili f_n2=1.0; uma( n > 1 ) {for(int k=2; k<=n; k++) {f_n = f_n1 + f_n2; f_n2 = f_n1; f_n1 = f_n; } } buyisela f_n; }
